IPC: G06F11/30
Filed: 2017-06-28
Abstract: A method and apparatus for notifying a central server that a computing device, such as a mobile phone, tablet or laptop is potentially damaged. One or more sensors of a computing device detect an event which may damage the computing device 90. The sensors measure a magnitude of a damage indicator associated with the hazardous event 92. The computing device determines that the magnitude of the damage indicator exceeds a threshold damage value for the computing device 94 and sending a message to a remote server indicating the computing device is potentially damaged 96. The damage indicator may be one of force of impact, or the sensor may detect the presence of smoke, CO2, or moisture. The threshold may be set according to the probability that a component is damaged, and may be adjusted depending on the duration of the event. The server may transmit repair instructions to the device.

Title: Microfluidic device having offset, high-shear seeding channels
Inventor: KAREL DOMANSKY
IPC: C12M3/04
Filed: 2016-04-08
Abstract: A microfluidic device for determining a response of cells comprises a microchannel and a seeding channel. The microchannel is at least partially defined by a porous membrane having cells adhered thereto. The microchannel has a first cross-sectional area. The seeding channel delivers a working fluid to the cells within the microchannel. The seeding channel has a second cross-sectional area that is less than the first cross-sectional area such that a flow of the working fluid produces a substantially higher shear force within the seeding channel to inhibit the attachment of cells within the seeding channel. And when multiple seeding channels are used to deliver fluids to multiple microchannels that define an active cellular layer across the membrane, the seeding channels are spatially offset from each other such that fluid communication between the fluids occurs only at the active region via the membrane, not at the seeding channels.
